E36 M3 Dyno Sheet Library

[Foda420]

My first time ever on the dyno today, pretty happy with how I did. According to the shop owner his dyno reads a bit low although I came in better than I expected. He asked me what they make at the crank stock, and what I had done. I told him I'd be happy with anything over 210 and he asked how I'd feel when it read 195. He was pretty impressed, joking with the other mechanic that me and the other guy there were the only ones that hadn't been disappointed on their dyno. Other guy had an E30 325is that put down 144/144.

How have all of you prepped your car for the dyno?

I'm running mine tomorrow, 3 pulls, and stock.

Definetly removing whatever is in my trunk, including the spare tire. Anything else?

Drive the piss out of it to try and get the DME to set an aggressive adaptation. Weight will make no difference whatsoever on a dyno.

[98M3rt]

How long will it take for it to learn my aggressiveness? Does the DME change if I drive aggressively the night before?

$20 for 3 pulls on a mobile DynoJet. Car is completely stock with a new Mann Air Filter in it (if I would have removed it I probably would have had at least 5hp more). Oil change about 1k miles ago, brand new wheels.

pulls were back to back and power dropped each pull(As it did on pretty much every other car.) inadequate fan maybe?


a little misfire on one pull(happens occasionally)
anyways, torque seems a bit low however they called that dyno the "heartbreaker"

torque seems to hold quite flat though especially compared to most.Hp is still climbing all the way till cut off which seems different than other cars with similar mods(they flatten before cut off as torque is dropping more significantly)
vanos seems to work fine though its still original(not rebuilt or changed). original coils and o2 sensors too.
You cant dyno race but last yr(before some other stuff Ive done since) the car trapped 101 mph.

E46 m3 with evolve tuned and ebay headers did 287 whp to give you a comparison. (another stock one did 269).
Hp Im ok with ..torque Im a little confused with. Yes its an s52.

no thoughts on my less than stellar torque ouput?

no thoughts on my less than stellar torque ouput?

I'd say it depends on the dyno. If you go back a couple pages, you'll see some dyno results I posted. My friend's M3 with very similar mods to yours made 210tq, and less HP than you did on our local "heartbreak" dyno. My car with more intake mods, a reflash and no headers only made 231/224. This was all in blazing FL heat and humidity though. I'd say if you're on stock tune and a very low reading dyno, you shouldn't be that concerned. Also a stock tune E36 trapping 101 makes me upset mine only trapped 102, almost 103.

[breakfast]

very good points. It is a bit of waste to compare dynos. The only mod Im looking for next is a flash/tune of some kind. If it can bring a bit of mid range torque back up Ill be happy.
thanks for the insight.

Nice power. That is S54 power from an S52. Which Shrick cams, the older mild or the newer sport? At what RPM was peak power made and what is the rpm limit?

[jakermac]

Those are the sort of numbers I'm hoping for from my build. What engine management/tuning did you use? Anxiously waiting to see the plot! Ditto on the rev limit!

How much would an S50 give up power wise over the S52? 10whp/10ft/lbs? More? Less? All else the same, just the reduction in displacement. What about an 84 x 89.6 (M54B30 internals in an M50/M52 block)?

[Bimmerman535i]

Well....it depends. The torque advantage is too big to ignore. 10whp/20ftlbs is about right, across the board.

I think you could get an S50 with all the bolt ons (no ITBs) to about 235-240whp max, but you will struggle to break 220-225tq.

S52s with same level mods are 245-250whp and 230+tq.

What cams are you using?

[BMWJNKY]

Does anyone know why there is a small flat spot in HP around 4K RPM with these engines? I see it in a lot of the dyno graphs in this thread and I can feel my car have a slight hesitation around that RPM when accelerating. I never experienced this hesitation with my '95 M3 but I feel it in my '97 and have had a couple customers at the BMW shop I work at mention a slight delay in acceleration around 4K RPM with their cars.

[kovrol]

maybe the vanos steppings...

[savannah996]

Just reviewing the last page here, why are our S52's signing off at 6000 rpm? Is it tuning? Certainly not a pumping issue, we have people with 3" exhausts and 3.5" mafs, M50 intakes and cams. I would think a Shrick cam would be timed for high rpm power right?
Is it tuning? Fuel pressure/volume inadequate? ( I didnt see any upgraded fuel pumps) Does everyone maintain 3.5 bar to 7k?

[kovrol]

cause the S52 is a "mid-range" torque engine, you can switch the power to higher rpms with sharper cams like Schricks and Sunbelts, but you will give up the low and mid range. Schricks are the best for street and track, sunbelts give a lil bit more power at top but loose a lot of torque around 3-4k rpm. There are a thread with approx 290cams, as I remember that car has euro M3 power at top end, but useless under 4-5k rpms...so not for daily drive.

Car has a non-functional VANOS, as seen by the lack of low end power/torque. The early SSAC headers have an atrocious bend on one of the cylinders that basically makes a 180 degree bend and folds in on itself..it is laughable.

Overall, I am fairly pleased all things considered.


**No wideband was on the car for these pulls**

Guys, somebody knows that the DynoDynamics - AWD 450 DS Quad retarder Chassis Dynamometer measures high or low? I will go to dyno my car on this type, because a few days ago I was on an "individually" made dyno and it measured 281WHP and I think its a little bit high for an S50B32 with SS race system, BMC CDA and propably the ECU got chipped cause it redlines at 7800rpm instead of 7400.

[damnboy37]

^That looks about right
